Welcome to Hamilton Construction
From its beginnings in 1939 as a small firm installing concrete road and irrigation systems, Hamilton Construction Co. has grown to become one of the West's leading heavy civil construction contractors. In recent years, our work has focused on transportation projects with an emphasis on major bridge projects, highway interchange, transit, rail, marine, and concrete structural components. Our proven track record of quick response and reliability makes us the first choice of many public agencies and private firms throughout the Western states facing time-critical and emergency situations. We have successfully met and exceeded the demands of Oregon, Washington, Colorado and Alaska Departments of Transportation, TriMet and a diverse group of private customers. Many of our clients have depended on us for decades as their contractor of choice.
Hamilton excels in the successful completion of highly technical projects in a variety of challenging environments ranging from the most densely populated, high traffic urban zones of the I-5 corridor in North Portland, to the most remote regions of Alaska, to structures located in highly sensitive and treasured habitat and recreational areas. Bridges, railroad trestles, cofferdams, highway interchanges, transit projects, specialized foundation work, overlays, project management, and more are part of Hamilton's everyday work.
Our bonding capacity, inventory of construction equipment, and material resources provide us the ability to successfully respond to today's most demanding jobs.
We are experienced with the full range of project delivery systems including Design-Build, CM/GC, and Design/Bid/Build.
